, Referring Yto': Figures I 'to -16 of the.V drawing the jack Yincludes a circular v-base "10 'having formed' integral with'its upper face a solid Averi tically disposed f sustaining member i 11 provided at .its topwith anfaxially arranged upstanding lug l2. Thel member'll anddugl'zare of circular contour in crossA section. Themember 11 isdisposed concentricallywith respect to the base 10.

`Mounted upon the base 10. is a vertically-disposed sleeve'13 into' the lower erid` of which extends the member; The latter maintains the 'sleeve13-in1an upstanding position. vThe :upper portion 14 of sleeve'13'is reduced and inset to `provide an annular shoulder 15 for apurpose to be referred to. ".The sleeve13 inproximity to its ylower end is; formed yon onesidezwith a .length- `Awise extending'rectangular slot16 havingone f .its side edges formed With'ratchet teethv 17.

nection see Figure 1.

its lower portion a bracket 19 in which is provided as at 19 one end of a foot operated lever 2D which cooperate with the sectional work clamping element to be referred to. The lever 20 extends through an opening 2l (Figure 3) in sleeve 13, across the latter and through slot 16. The non-pivoted end of lever 20 has a foot tread 22. The lever 20 is diagonally disposed with respect to the axis of sleeve 13.

Seated upon the shoulder 15 is a coupling collar 23 having al reduced upper part 24 formed with internal threads 25. The collar 23 is provided with diametrically disposed openings 26 having the walls threaded. The collar 23 en- Compasses and extends above the part 14 of sleeve 13. Binding screws 27 extend through Vand threadedly engage with the walls of openings 26,

"as well as abut part 14 of sleeve 13.

Threadedly engaging with the reducedupper end of the collar 23 is the lower end of the main .section 28 of a tubular support. The latter also includes a pair of tubular auxiliary sections 29, The

imposed relation with respect to the section 28. The latter is of greater length than the other sections of the support. The section 29 is of The lower end of The upper end of the section 28 is rabbeted on its inner face to provide a shoul- Yder 34 and a flaredpart 35. The member 31 is in the'form of a ring havinga depending tapered annular flange 36 spaced adjacent to the edge of the ring to provide a shoulder 37. The member 31 is selectively mounted upon and extends into the upper end of a section 28, 29 or 30. The section 28 and member 31 coact to support the head structure, to be referred to when the vertically adjustable abutment element is in its normal or non-adjusted position, and in this con- The sections 28, 29 and .member 31 coact to support the head structure when the abutment element is in its 'rst position of adjustment and in this connection attention is directed to Figures 1 and 2. The sections 28, 30 and member 31 coact to support the head lstructure when the abutment element is in its second position of adjustment and in this connection it will be stated that the section 30 would be substituted for section 29, and be arranged relative to section 28 and member 31 in the same manner as section 29 is shown in Figures 1 and 2. The head structure intermediate its ends seats upon the upper end of the tubular support andis revoluble relative to the latter.

A tubular combined guide and support element 38 is mounted on the top of member 11. The lug 12 extends upwardly into the lower portion of element 38. The latter is of a length to ex'- tend from member 11 to the bottom edge of section 28 of the tubular support. Fixedly'secured to the element 38 and disposed diametrically thereof is a sustaining pin 39 for a purpose to be referred to;v ,Positioned above and' in spaced relation to the pin 39 is av pair of diametrically opposed openings 40, 41 formed in the element 38 and which align respectively with a pair of diametrically opposed openings 42`, 43 formed in the sleeve 13. Positioned above and in spaced relation tothe openings 40, 41 respectively is a pair of diametrically opposed openings 44, 45 formed inthe element 38 and which align respectivelywith a pair of diairietrically opposed-openings 46, 47 formed in the sleeve 13. Positioned above and in spaced relation to the openings 44, 45, the element 39 is provided with a pair of spaced parallel lugs 48, 49 formed with aligning openings 50, 51 and which align respectively with a pair of diametrically opposed vertical slots 52, 53 formed in the part 14 of sleeve 13. The slots 52, 53 have their upper ends open. The purposes of the lower group of aligning openings 40, 41, 42 and 43; the upper group of aligning openings 44, 45, 46 and 47; and the aligning openings 50, 51 and slots 52, 53 will be hereinafter referred t0. The collar 23 has clearances 54 which are associated with openings 50, 51 and slots 52, 53.

Arranged within element 38 and extending into the sectional tubular support is a vertically adjustable abutment element 55 for the head structure to be hereinafter referred to. The element 55 is in the form of an elongated solid bar 56 having an intermediate stretch 57 of semi-circular cross section, an upper stretch 58 and a lower `stretch 59. The-stretches 58, 59 are of circular cross section. The stretchV 58 is of greater length than stretch 57 and the latter is of greater length than stretch 59. The stretch 56 is formed with a flat face which is toothed throughout to provide a rack, as at 60. The bottom edge portion of stretch 58 and topv edge portion of stretch 59 extend beyond the rack 60 and constitutes stops for arresting the vertical movement in opposite directions of the stretch 57 by an adjusting device, to be referred to for the element 55. The top of stretch 58 is rounded, as at 61. tom of stretch 59 is squared, as at 62 and formed with a transverse groove 63.

The sectional head structure is generally indicated at 64 and includes a lower section in the 'form of a body part 65 having an oval shaped upper end and its remaining portion of circular cross section. The body part 65 has a reduced lower portion 67 to provide a peripheral shoulder or seat 68 intermediate its ends. The body part 65' in itsv upper portion is formed with a tapered socket 69 and at its lower end has a semicircular lrecess 70. The wall of the latter constitutes a `bearing surface. Formed integral with and flush with the bottom of body part 65 is va depending tubular stem 7l of uniform inner diameter having the upper end of its inner face merging into the lower end of'the wall of recess 70. Thehead structurel 64 also includes an intermediate section-72 formed of a tapered oval shaped body part 73 of greater area than the top of 'body part 65 so as to project laterally from the latter. The section 72 has a tapered shank 74 depending from the bottom of body part 73 and disposed in the socket 69. Extending upwardly from the top of body part 73 is a tapered stem 75 which is slightly offset with respect to shank 74. The upper face of body part 73 slightly inclinesfdownwardly horizontally from one end to the other. The head structure 64 also includes an outer section 76 in the form of a metallic last consisting of a head piece 77 in the form of a last, a short' shank 78 depending thereof and a tapered socket 79 opening at the bottom of the shank. The socket 79 receives the stem 75. The bottom of the shank 78 is `substantially of the same area as the top of body part 73. When the head structure64 is arranged relatively to the sectional tubular support the shoullder 66 seats upon the rearing member 31, and the stem 7l depends into the section 28 of such support.
